What happened?

When generating the project with the following command:

quarkus create app org.acme:hello-flow \
  --extension=resteasy-reactive-jackson,io.quarkiverse.flow:quarkus-flow

We got a conflict between quarkus-rest and quarkus-flow codestarts.

Minimal reproducer

quarkus create app org.acme:hello-flow \
  --extension=resteasy-reactive-jackson,io.quarkiverse.flow:quarkus-flow
